摘　　要：【目的】城市土壤食物网(urban soil food web)主要表征为由鞘翅目、弹尾目、甲螨亚目等土壤节肢动物构成的多营养级生物交互网络,该网络通过碎屑食物链与捕食性食物链的能量传递机制参与物质循环和能力流动,在生态系统中起着重要的作用。在生态功能层面上,城市土壤食物网一方面积极同化土壤中各种有用物质以参与自然界碳氮循环,另一方面又将其代谢产物归还到土壤环境中进而影响土壤肥力演替。为了明晰城市土壤食物网研究发展现状,从中找出城市土壤食物网各热点间相互关系。【方法】运用CiteSpace和VOSviewer软件,对2004—2024年间WoS(Web of Science)外文数据库和CNKI数据库中的关键词、作者与机构进行可视化聚类分析。【结果】(1)分析表明,该领域外文文献发文量呈现阶段性增长的趋势,中文文献显示前十年间相关研究发展迅速,之后研究热度不断下降,但在相关领域有所突破;(2)通过对核心文献共被引次数和关键词突现及聚类分析发现,城市土壤食物网研究领域不断拓展,扩展深度不断增加。【结论】在2004—2024年期间,以调查群落结构、生物多样性及功能类群为主;近年来环境变化使得城市绿地、生态系统以及环境因子等成为突现词,城市土壤食物网与城市生态系统、城市生境破碎化之间的关联也成为当前研究的创新点。[Objective]Urban soil food web is mainly characterized by a multi-trophic biological interaction network composed of soil arthropods such as Coleoptera,Collembola and Oribatida.This network participates in material circulation and capacity flow through the energy transfer mechanism of detrital food chain and predatory food chain,and plays an important role in the ecosystem.At the level of ecological function,on the one hand,urban soil food web actively assimilates various useful substances in the soil to participate in the natural carbon and nitrogen cycle,on the other hand,it returns its metabolites to the soil environment and affects the succession of soil fertility.The aim of this study is to clarify the current status of urban soil food web research development.[Method]This paper uses CiteSpace and Vosviewer softwares to visualize and cluster the keywords,authors and institutions in the WoS(Web of Science)foreign language database and CNKI database from 2004 to 2024.[Result](1)The results showed that the number of foreign language literature issued in this field showed a trend of stage-by-stage growth,and the Chinese literatures had a rapid development of related researches in the first decade,followed by a decreasing research heat,but there was a breakthrough in the related field.(2)Through the analysis of core literature co-citation and keyword emergence and clustering,it was found that the research field of urban soil food web had been expanding and the depth of expansion had been increasing.[Conclusion]From the beginning of the 21st century,the investigation of community structure,biodiversity and functional groups was the main focus;in recent years,environmental changes had made urban green spaces,ecosystems and environmental factors become emergent words,and the association between urban soil food webs and urban ecosystems,urban habitat fragmentation,had also become the innovation point of the current research.
